reorder repo parameters last
Many functions took the repo as their first parameter. Changing it consistently to be the last parameter allows doing some useful things with currying, that reduce boilerplate. In particular, g <- gitRepo is almost never needed now, instead use inRepo to run an IO action in the repo, and fromRepo to get a value from the repo. This also provides more opportunities to use monadic and applicative combinators.
